Principle
Generally used in hazardous locations where explosions may occur. Due to the presence of flammable and explosive oils, gases, dust, etc., in the surrounding environment, contact with electric sparks can cause explosions. Therefore, explosion-proof heaters are required for heating in such situations. The main explosion-proof measure of the explosion-proof heater is an explosion-proof device in the junction box, which eliminates the risk of electric spark ignition. For different heating scenarios, the explosion-proof level requirements of the heater vary, depending on the specific situation.
Scope of use:
Suitable for heating air, oil, water, chemical media, hot pressing molds, melting salts, alkalis, and low melting point alloys. It has the characteristics of high thermal efficiency, long service life, high mechanical strength, easy installation, safety and reliability.

Lead terminal materials are generally two types: stainless steel and free-cutting iron.
Sealing materials include: epoxy, silicone, glass, etc.
Process:
The heating tube is made by inserting electric heating wire into an outer tube (carbon steel tube, titanium tube, stainless steel tube, copper tube), filling the gaps with magnesium oxide powder that has good thermal conductivity and insulation, then shrinking the tube, followed by heat treatment (not required for some tubes), and finally processing into various shapes required by the user. It has a simple structure, high thermal efficiency, good mechanical strength, and good adaptability to harsh environments. It can be used for heating various liquids, acids, alkalis, and salts, as well as for melting low melting point metals.
Installation form:
Based on the design concept of high efficiency, energy saving, convenience and practicality, we combine the actual usage conditions of users: large storage tank volume but small oil extraction quantity at a time, and the discontinuous and irregular nature of operations. Therefore, it is not necessary to heat the entire storage tank during heating. This saves electrical energy while achieving fast heating. Local or partial heating methods can be used to heat part or local media: the design concept of instant heating, no heating when not in use. Referring to industry and international standard design specifications, combined with our company's many years of practical production experience, we design instant-heating pump-out electric heaters.
